Oral calcium-loading test in rickets and in neonatal tetany: effect of vitamin D.
In an oral calcium-loading test performed on 10 infants with vitamin-D deficiency rickets and low fasting calcium levels, a comparison of results before and after therapy showed that vitamin D raised the serum calcium level at each stage of the test and altered the response so that a more rapid and substantial rise and fall in serum calcium occurred.The effects of vitamin D therapy on newborn i...
متن کاملAminophylline Infusion Induced Excretion of Magnesium During Magnesium Loading Test in Critically Ill Patients
The aim of this study was to investigate the prevalence of Mg deficiency and effect of aminophylline infusion on urine magnesium concentration after magnesium loading test (MLT). To determine serum Mg, venous blood specimens were obtained just before the first MLT. Two MLTs were performed. The first one was done before starting aminophylline infusion and the 2nd one was done du...
متن کاملEffects of bicarbonate, citrate, and phosphate loading on performance.
Since the 1930s, scientists have attempted to determine if increasing the body's ability to buffer metabolic acids will enhance physical performance. The buffer of major interest has been bicarbonate; to a lesser degree, citrate and phosphate salts have been investigated. In theory, the buffers facilitate performance by decreasing the accumulation of hydrogen ions that would otherwise presumabl...
متن کاملPractical considerations for bicarbonate loading and sports performance.
Consumption of sodium bicarbonate (300 mg/kg 1-2 h before exercise) can temporarily increase blood bicarbonate concentrations, enhancing extracellular buffering of hydrogen ions which accumulate and efflux from the working muscle. Such 'bicarbonate loading' provides an ergogenic strategy for sporting events involving high rates of anaerobic glycolysis which are otherwise limited by the body's c...
متن کاملThe Calcium Content of Muscular Tissue during Parathyroid Tetany
Excepting the observations of Loughridge (1) we have been unable to iind data on the calcium content of striped muscle during parathyroid tetany. He found much less calcium in dog muscle during tetany (two animals) than in the muscles after recovery from tetany through treatment with calcium chloride or parathyroid extract (three animals). Katz (2) found 0.0685 parts of calcium per kilo of norm...
